Fixed blades are fixedly connected to the inner wall of the mixing tank. An inlet pipe is fixedly connected to the top of the mixing tank, and a protective hopper is fixedly connected to one end of the inlet pipe. A housing is fixedly connected to one side of the mixing tank, and a fixed rod is fixedly connected to the inner wall of the housing. A motor is fixedly connected to one end of the fixed rod, and the output shaft of the motor is fixedly connected to a transmission shaft via a coupling. This ink mixing and proportioning device achieves the goal of good mixing effect, solving the problem of poor mixing effect in general printing ink mixing and proportioning devices. It greatly reduces mixing time, thereby improving the working efficiency of users and meeting their needs, making the process of using the ink mixing and proportioning device more convenient.

[0003] In actual use, due to the fixed setting of the stirring blades, the stirring device can only mix printing inks of a single viscosity. When mixing different batches of printing inks with high or low viscosity, the distance between the stirring blades will affect the mixing effect of the printing ink, causing the printing ink to separate into layers, resulting in uneven mixing of the printing ink and reducing the mixing efficiency of the printing ink.

[0004] Therefore, a printing ink mixing structure is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printing ink mixing structure, comprising a mixing tank, supporting legs, and a top cover. The bottom of the mixing tank is fixedly connected to the supporting legs, and the top of the mixing tank is threadedly connected to the top cover.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Implementation examples, by Figure 1-5 The present invention includes a mixing tank 1, a support leg 2, and a top cover 3. The bottom of the mixing tank 1 is fixedly connected to the support leg 2, and the top of the mixing tank 1 is threadedly connected to the top cover 3. The top of the top cover 3 is fixedly connected to the top of the top cover 3. The output end of the servo motor 4 passes through the inner wall of the top cover 3 and is fixedly connected to a locking block 10. The top of the top cover 3 is fixedly provided with a feed inlet 5 for adding raw materials.

[0025] Specifically, a discharge port 6 is fixedly installed at the bottom of the mixing tank 1, and an electronic valve is fixedly installed on the side of the discharge port 6 to control the opening and closing of the discharge port 6; before and after use, the opening or closing of the discharge port 6 is controlled by opening or closing the electronic valve.

[0026] A connecting shaft 7 is fixedly connected to the inner wall of the mixing tank 1. A rotating shaft 8 is inserted into the inner side of the connecting shaft 7. A mixing assembly is provided on the side of the rotating shaft 8. The mixing assembly includes a screw 11, a stirring blade 14 and a sliding plate 15. The sliding plate 15 is slidably connected to the outer side of the slide groove 16. The screw 11 is threadedly connected to the inner wall of the sliding plate 15. The stirring blade 14 is fixedly connected to the outer side of the sliding plate 15.

[0027] Specifically, a slot 9 is provided on the top of the rotating shaft 8, and the size of the locking block 10 is adapted to the size of the slot 9. The locking block 10 is engaged with the inside of the slot 9. The connection between the servo motor 4 and the rotating shaft 8 is realized through the engagement of the locking block 10 and the slot 9.

[0028] Specifically, a groove 16 is provided on the inner wall of the rotating shaft 8, and threaded holes 17 are evenly provided on the side of the groove 16 on the inner wall of the rotating shaft 8; a screw 11 is threadedly connected to the threaded hole 17 to fix the sliding plate 15; through the connection between the screw 11 and the threaded hole 17, under the connection action of the sliding plate 15, the sliding plate 15 slides along the groove 16, which facilitates the movement of the stirring blade 14, thereby adjusting the distance between adjacent upper and lower stirring blades 14. When mixing printing ink with high viscosity, the distance between adjacent upper and lower stirring blades 14 can be reduced to increase the mixing density and avoid the phenomenon of printing ink mixing and stratification. When mixing printing ink with low viscosity, the distance between adjacent upper and lower stirring blades 14 can be appropriately increased to improve the mixing effect.

[0029] Specifically, the stirring blade 14 is engaged with the outer side of the scraper 13, and the stirring blade 14 can slide along the outer side of the scraper 13; the upper end of the rotating shaft 8 is fixedly connected to the connecting rod 12, and the scraper 13 is inserted into the outer side of the connecting rod 12.

[0030] Working principle: During operation, the top cover 3 is removed from the top of the mixing tank 1, and the discharge port 6 is kept closed. The raw materials are added to the inside of the mixing tank 1. Then the top cover 3 is installed on the top of the mixing tank 1. During this process, the locking block 10 of the output end of the servo motor 4 is engaged with the inside of the slot 9. Then the servo motor 4 can be started, so that the output end of the servo motor 4 drives the rotating shaft 8 to rotate, which in turn drives the mixing component to rotate.

[0031] Meanwhile, during use, ink can be added through the feed inlet 5, and the printing ink can be stirred by the rotation of the stirring blade 14 to ensure that the printing ink is mixed evenly. The rotation of the rotating shaft 8 can drive the scraper 13 to rotate, so that the scraper 13 stirs the printing ink attached to the inner wall of the mixing tank 1, avoiding ink adhesion that causes color difference.

[0032] When mixing printing inks with high or low viscosity, the rotating shaft 8 can be removed and connected to the threaded hole 17 via the screw 11. Under the action of the sliding plate 15, the sliding plate 15 slides along the groove 16, facilitating the movement of the stirring blade 14. This allows adjustment of the distance between adjacent stirring blades 14. When mixing printing inks with high viscosity, the distance between adjacent stirring blades 14 can be reduced to increase the mixing density and prevent the printing ink from separating during mixing. When mixing printing inks with low viscosity, the distance between adjacent stirring blades 14 can be appropriately increased to improve the mixing effect, ensure uniform mixing of the printing ink, and improve the mixing efficiency of the printing ink.

[0033] When mixing is complete, the top cover 3 can be removed, and then the rotating shaft 8 can be removed as a whole. The scraper 13 can be easily removed and cleaned by connecting the connecting rod 12 and the scraper 13. At the same time, the mixing blade 14 can be easily disassembled and cleaned by the connection between the screw 11 and the threaded hole 17, ensuring the cleanliness of the mixing device.
